LG 55LM7600-UA has horizontal lines

[as2114]

I have an LG 55LM7600-UA and it has horizontal even lines that start from the left (pronounced) and about 3/4 of the way to the right, the lines fade out to no lines. I have reseated the 2 cables from the main board to the display, on both sides and no change. I also had sound before, but all of a sudden, the sound went out and I can't get the magic remote to work, other than the power on. Any idea on some other troubleshooting tips? Is this a main board problem or display panel? Any advice is appreciated.
